IMPEOVED WNDOW-BLIND FASTENINC T0 ALL WHOM IT MAY CONCERN:

Be ih known that I, GEORGE B. MELCBEB., of Salem,.county oi' Essex, State of Massachusetts, have invented u new or improved Device for Fastening Window-Blinds; and I do hereby declare that the following is a .full and exact description thereof, reference being had to the accompanying drawings, end to the letters of reference marked thereon.

The nature of my invention consists in what I term a rotary slide-button, which is fastened to me face or inside of the bottom rail of the blind by a. screw, nail, or their equivalent. The said'rotary/slide-button is constructed with a. slot in or near the middle of it. Throughfsaidhole the screw or its equivalent passes which fastens the button to the blind, thus allowing the button to have a. sliding and also a. rotary motion. One end of said but-ton is made heavier than the other; that is, it has a foot or projection, used for two purposes, one being to keep the end with the projection always down when the buttpn ceases to turn, or, inother words, when its rotary motion ceases. The other is to give the lower end of said button a. surface, which is made convex from back to front, as it hangs attached to the blind. The button has a notch across its extreme convex end, running from right to left, or at right angles with the face, when attached to the blind, for the purpose of catching on to a. stnd'in the window-stool, when the blind is in the act of being shut, and also upon ahook in the house, when the blind is in the uct of being opened. It also may have a notch in the top or smaller end of 'said button, running from front to reer, for the purpose of inserting e screw or its equivalent, through the same, into the rail of the blind, for the purpose of fastening the button, when desired, in such e. manner that it cannot be turned or raised, thus melting the blind secure when either open or shut. The lower or projecting end of seid button has s convex or inclined surface from back to front.

In shutting the blind, the convex fece of the, end of the button strikes the stud in the window-sill in an oblique direction, causing the button to rise perpendicularly until the blind is fully closed, when the button will drop down upon the catch or stud in the window-sill, und thus securing the blind. In opening the blind, the button oper-.ttes the same in respect to the outer catch.

l' make my fastening of any proper materiel, and of any length, width, or thickness, according to cenvenicnce, its ferm being es is fullyset forth in the accompanying drawings, Drawing No. 1, with a slot B, notch ci, convex end c e, projection g, or the same end the notch A; end scid fastening is attached to the lower rail of the blind l?, es is shown in Drawing No. 2, by a screw, c, or its equivalent.

A thin. plate may be used, of any substance, between the blind` end the button;

What I claim as my invention, und desire to secure by Letters Patent, isv l The aforesaid rotary slidebuttcn, as made with e. slot, B, projection g, notch d, and convex face e e, substnntielly es described.
